Communication device with warning function and communication method thereof

Abstract

A communication device with an audio database comprises an audio receiving module, a locator module, an audio identification module and a notification module. The audio receiving module calculates the strength of the at least one signal, the locator module determines whether each of the strength exceeds a predefined value and determines the directionality of the at least one audio signal in accordance with the strength of the at least one audio signal. The audio identification module compares the audio signal with audio modules in accordance with characteristics parameter to issue a warning.

1 . A communication device with an audio database, comprising:
 a microphone array that detect at least one audio signal;   an audio receiving module that receives the at least one audio signal and calculating strength of the at least one signal;   a locator module that determines whether the strength exceeds a predefined value and determines a directionality of the at least one audio signal in accordance with the strength of the at least one audio signal;   an audio identification module that compares the audio signal with audio modules in accordance with characteristics parameter, wherein the audio modules and the characteristics parameter are stored in the audio database; and   a notification module that issues a warning in accordance with the selected audio module.   
     
     
         2 . The communication device of  claim 1 , wherein the locator module samples the audio signal to select one of the audio modules corresponding to the sampled audio signal. 
     
     
         3 . The communication device of  claim 1 , wherein the warning can be selected from a group at least consisting of a man-shape icon, a vehicle-shape icon, a direction icon, and a vibration hint. 
     
     
         4 . The communication device of  claim 2 , wherein the warning can be selected from the group consisting of audio module stored in the audio database and the directionality of the audio signal. 
     
     
         5 . The communication device of  claim 2 , wherein the microphone array is capable of detecting a plurality of audio sources from different directions at the same time. 
     
     
         6 . The communication device of  claim 1 , wherein the communication device determining the directionality of the audio sources by comparing the strength of the audio source with each other. 
     
     
         7 . A communication method for warning issue comprising:
 receiving an audio signal detected and calculating the strength of the audio signal;   determining whether the detected strength exceeds a predefined value;   determining a directionality of the audio signal in accordance with the strength of audio signal; and   sending a warning in accordance with the audio module to provide the originating direction of the audio source.   
     
     
         8 . The method of  claim 7  further comprising samplizng the audio signal in accordance with characteristic parameters and comparing the sampled audio signal with the audio modules to select an audio module corresponding to the sampled audio signal, wherein the characteristic parameters and the audio modules are stored in the audio database. 
     
     
         9 . The method of  claim 8  further comprising receiving multiple audio signals from the microphone array then comparing the strengths in accordance with a compliance rule list predefined and stored in the communication device 
     
     
         10 . The method of  claim 7 , wherein the warning can be selected from the group consisting of audio module stored in the audio database and the directionality of the audio signal. 
     
     
         11 . The method of  claim 7 , wherein the warning is a human shape, a vehicle shape icon, a direction icon, or a vibration hint. 
     
     
         12 . The method of  claim 11 , wherein the microphone array is capable of detecting a plurality of audio sources from different directions at the same time.
